IMPROVEMENT IN MECHANISMS FOR PRODUCING ROTARY MOTION.

Specification forming part 'of Letters Patent No. 127,682, dated June11, 1672.

Specification describing certain Improved The said machine may beoperated by manual force or by any other power, and is adapted for oneor the other, according to the particular purpose it is destined toserve.

My improved machine has two crank-shafts. One of these I call the firstshaft, and the power is applied thereto and is transmitted throughvibrating levers to the second shaft, from which the rotative force istransmitted to perform its work, as follows: The said first shaft isfurnished with two cranks placed at right angles to each other and ofequal length. Two connecting-rods of equal length are united at one endto the cranks of the aforesaid shaft, and connect them to two levers,which are also of equal length, and are equally divided into theproportions hereinafter specified. Two other connecting-rods areattached to the said levers and to the cranks of a second crank-shaft,whose cranks are also arranged at right angles to each other. Thesecranks are shorter than the first cranks, and their length bears thesame proportion to that of the first cranks as one division of thelevers bears to the other division. The power is applied to the firstcrank-shaft in any convenient manner, and the rotation of the cranks ofthe said shaft through the connecting-rods imparts avibratin g motion tothe levers, and these, through the other connecting-rods and cranks,cause the rotation of the second-shaft, which is connected in anysuitable manner to the machinery, apparatus, vessel, or vehicle to beoperated or moved.

The manner in which I carry my said invention into practice isillustrated in the accompanying drawing, of which- Figure 1 is a plan ofmy improved machine,

and Fig. 2 is a side elevation of the same.

Like letters indicate the same parts throughout the drawing.

The whole of the mechanism is supported on a suitable bed orfoundatioma, by a strong framing, a, of cast-iron or other suitablemetal. I) is a metal shaft, which may be of any suitable length anddiameter, and to which the power is applied by a crank-handle, b, or bya wheel, pulley, or drum fixed on the shaft in place of the said handle.b is a flywheel. 0 d are two cranks formed on the said shaft. 6 f arethe two connecting-rods which connect the said cranks to the extremitiesof the two levers g h, as clearly shown in Fig. 1. These levers havetheir fulcrums at g h. c j are the other connecting-rods, which connectthe levers g h to the two cranks k l of the second crank-shaft m, asshown in the same figure. From this second shaft the power iscommunicated to the machine or apparatus to be operated, or applied toany other work to be performed, the speed at which such work isperformed being determined by the gearing or connections through whichthe power is transmitted. I may provide the shaft m with a drum orpulley, n, as shown, or with a toothed wheel, or clutch, or other likecontrivance for connecting the said shaft with the machine or part towhich the power is to be communicated. The first cranks c d have fourtimes the length of the second cranks is Z, and the levers are dividedin the proportions of four to one. The connecting-rods should also befour times the length of the cranks to which they are attached. Ifdesired, the proportions of the levers and cranks may be more or lessthan four to one, but the machine will not then work so advantageouslyas when these proportions are maintained. The diameter of the shafts,and the dimensions of the cranks, rods, and levers, and also thestrength of the framing of each machine must be such as will best adaptit to the work it is destined to perform and the power it will have todevelop.

Claim.

A machine with two crank-shafts or sets of cranks, in combination withthe vibrating levers and connecting-rods, which cranks, 1evers and rodshave the proportions herein specified, and. which are so arranged andconnected together that the rotative force applied to the first shaft istransmitted to the second shaft, and may be applied for drivingniachinery or for'other purposes, as herein set forth.
